Description

  The present invention relates to outerwear with enhanced breathability.

  The garment is provided with an air passage during the treatment of the slightly air permeable face material or the inner material, thereby allowing ventilation. As described also in the publication EP 0 648 438, a known example is a vent provided with a metallic eyelet in the shoulder region. However, the ventilation effect of this means is insufficient.

  The publication describes that in the case of watertight clothing, the opening is often covered with a tab made of the same material as the face material. This tab covers the vent opening so that effective ventilation is no longer provided.

  The goal of the ventilator is to maximize air exchange. If the water vapor formed by perspiration cannot escape through the garment, the air humidity rises inside the garment until the water vapor condenses. The clothing worn under this garment gets wet.

  The use of air-tight and water-tight water vapor permeable membranes (membranes), which are designed to extract the steam generated by perspiration outward, is not always a sufficient measure. This membrane capacity is inadequate, especially during increased physical fatigue or where there is increased sweat secretion.

  U.S. Pat. No. 6,263,511 describes a breathable garment. In the area of enhanced sweat formation, there are holes on the inside. Through this hole, the evaporated sweat can enter the intermediate chamber more quickly. The surface material is provided with holes for ventilation. In this case, in order to obtain water tightness, intrusion of liquid from the outside is prevented. This is achieved by a multilayer structure. Below the surface material is a layer of hydrophilic material that can absorb sweat, and below this layer is another layer that forms an intermediate chamber. In this intermediate chamber, the steam is conveyed upward by a chimney effect toward the vent hole provided in the outer material. The hole can be closed by different structural means, for example valves, so that liquid cannot enter from the outside through the hole. A known disadvantage of this invention is the high constructional effort to achieve ventilation and thus the production engineering effort.

  EP 0 648 438 discloses a water-tight passage covering of passage openings, in particular vent openings for garments. This opening has on the outside a tab fixed on one side. This tab completely covers the opening in the sagging state. Another configuration is a vent opening having a slide fastener that can open and close the opening. This configuration is not covered by tabs. Air can flow through the opening without interruption. A tab opening maintaining device can be provided for a configuration including a tab. This tab opening maintenance device allows air to flow through the opening without obstruction.

  This drawback of the vent opening corresponds to that of the vent opening disclosed in the following publication EP 1002470 "Wear with venting device". During increased sweat secretion due to physical fatigue, clothes worn under watertight or airtight clothing get wet. Functional materials are certainly permeable to vapors, but not permeable to condensed water. The breathability of this material is limited and cannot exceed the specified vapor transfer rate. Sweating exceeding this rate forces condensation. Here too, the possibility of improving the breathability by a vent opening that can be opened and closed as desired is recognized. The ventilation device is here formed as a slit. A spring clip is fixed to the slit or the fastener device along the slit. With this spring clip, the ventilation opening is kept open in an open state.

  With a simple vent opening that is closable and formed in the form of a slit, the minimum distance between the two opposite sides of the opening is not guaranteed open. This can interfere with circulation. For example, an opening stabilized by a spring clip makes the body underneath the garment visible first and secondly unprotected and directly exposed to external climatic conditions and drafts. The additional cover again obstructs ventilation.

  German Offenlegungsschrift DE 7 00 400 discloses moisture-proof clothing with ventilation openings which are overlapped by the material part. This ventilation opening is released by the web. The web can be swelled by different means, for example tension bands or pockets (in which the web is inserted).

  Wear with a venting device is also disclosed in GB 2388297. Here, self-supporting ventilation passages open on both sides are used. This inherent stability of the ventilation passage is achieved by the use of bands or strips made of thermoplastic material or by a wavy groove profile.

  U.S. Pat. No. 4,731,883 discloses a garment having a vent opening. A tab-shaped cover is located above the vent opening. The cover lies flat above the opening and is closed or tunneled over the opening to allow for improved ventilation. The cover is held in a closed and open position, ie a tunnel-like position, by the hook and loop fastener.

  FR-A-1008240 discloses a jacket made of a water-tight material with a ventilation passage formed by a crease located in the back part. In this case, the crease is open at both ends, and extends upward to the inside of the collar.

GB-A-375207 discloses a venting device for clothing. The ventilation device is composed of an opening provided in the wear and a cover above the opening. This cover is fixed to the wear. The cover on the three sides is fixed to the wear on, for example, two sides and forms one opening with the wear material on the third side. The tension band allows the side that is not fixed to the garment to contract, which causes the cover to bend above the opening.

  The object of the present invention is to ensure that an effective and simple ventilation system for outerwear that improves breathability can also be used for different clothes, watertight and airtight sportswear and working wear. is there.

  In order to solve this problem, in the configuration of the present invention, the outerwear includes at least one ventilation device, and the ventilation device includes at least one ventilation opening and a cover, and the cover includes: Extending over the vent opening in the surface material of the wear, forming an opening with the surface material in at least one region, and the edge of the cover being bonded to the surface material in the remaining region; The cover has fasteners in at least one region having a predetermined spacing relative to the surface material between the regions where the cover is bonded to the surface material and forming an opening with the surface material. And the fastener tongue can close the opening and, in the open state, the fastener tongue is folded inwardly into the cover so that the cover is attached to the fastener tongue. It was so forms a curved stabilized.

  This ensures that the opening that the cover forms with the surface material is kept open. The fastener tongue is, in the simplest case, an extension of the cover. The edge of this extension is not bonded to the surface material and can therefore be folded inward into the cover. In order to ensure that the fastener tongue does not inadvertently close the opening that the cover forms with the surface material and stabilizes the curvature, the fastener tongue is desired by a suitable means such as a hook-and-loop fastener or snap fastener. It can be fixed in position. Thus, the fastener tongue not only serves to close the opening as needed, but in the open state, the cover is reinforced or stabilized by the second layer, so that the cover is a surface material. The opening formed together is reliably maintained open.

  The venting device is particularly suitable for watertight and airtight functional garments equipped with membranes. The cover of the venting device is bonded to the surface material at the bonding point to such functional clothes, thereby preventing water from entering. Bonding can be done by sewing, gluing, welding or another known bonding technique or a combination of these processes.

  The distance between the cover and the surface material may be substantially constant over the width and length of the cover, depending on the configuration, but may be larger than the edge area in the middle area of the cover, It may be reduced towards the edge that is bonded to the material. The distance between the surface material and the cover is preferably between 1 mm and 100 mm. Advantageously, the distance between the cover and the surface material is between 5 mm and 85 mm. In an advantageous configuration, the distance of the cover relative to the surface material is between 10 mm and 70 mm, particularly preferably between 15 mm and 50 mm.

  The shape of the cover and the vent opening can be freely selected. Circular, polygonal and even free shapes are possible. In terms of manufacturing technology, a substantially square or trapezoidal configuration is advantageous. That is, the venting device typically has four sides with two shorter sides and two longer sides. In this case, four sides of approximately equal length are also possible.

  In this case, the cover of the venting device, preferably on the four sides, is connected to the surface material on at least two opposite sides and forms an opening with the surface material on at least one side. . Thus, the cover may be open on two opposite sides. An advantageous arrangement is the fixing of the cover on three sides to the face material. This cover has only one opening in this case. The opening can be formed on one of the longer sides by a cover having a predetermined distance from the surface material and the surface material. Advantageously, the opening is realized on one of the shorter sides. Of course, it is also possible for the opening formed by the cover and the surface material to be formed on the longer side of the cover. In this case, the fastener tongues folded inward should sufficiently stabilize the cover, thereby ensuring that there is a predetermined distance between the cover and the vent opening.

  The cover formed by the cover material having a predetermined interval with respect to the surface material and the surface material may be basically directed in any arbitrary direction. It is particularly advantageous if the cover forms one opening downwards with the surface material, thus avoiding that rain can reach the inside of the garment via the vent opening.

  The cover is located on the surface material and is advantageously made of the same material as this surface material. However, this does not eliminate the use of other materials. This arrangement avoids the wearer being directly exposed to outside conditions and drafts. The vent opening may comprise a mesh so that the vent opening maintains its shape and is not pulled apart. This mesh is secured to the edge of the vent opening. Another possibility is to provide a transverse web which is advantageously made of the same material as the face material. It is also possible to cut out a plurality of vent openings side by side so that the web remains between the openings. If the ventilation openings cannot be pulled apart, it is at the same time guaranteed that the cover curved over the ventilation openings does not rest on the ventilation openings and does not disturb the ventilation.

  The cover is preferably stretched over the vent opening in an arcuate or semicircular shape. In this case, the opposite sides extend in parallel and are connected to the garment on three sides and form an opening with the surface material downwards, thus forming a vent tunnel. The cross section of this opening is substantially constant over the entire length of the venting device. In an advantageous configuration, the cross section of the opening expands downwards. In this cross section, the curvature of the cover is more strongly formed downward. Thereby, a stronger ventilation effect can be obtained.

  It is also possible that the opposite side connected to the garment extends antiparallel and is narrowed towards the vent opening. For enhanced ventilation effect, the opposite sides connected to the garment have the greatest distance from each other at the lower edge of the cover and the smallest distance from each other at the upper edge of the cover. It is advantageous to have. The opposite side collides at its highest point and can form a conical cover. The cover has one opening with the face material facing down. In this case, the cover is fixed to the surface material only at the side edges. The upper edge is omitted. Because the side edges collide at the highest point.

  Furthermore, a particular advantage of the above-described configuration of the venting device is that the venting device has functional characteristics that may be color stepped or characterized by color stepped seams. The design feature is realized.

The longitudinal axis of the venting device preferably extends parallel to the long axis of the body, but may extend at an angle of about 90 ° to the long axis of the body, and any It may extend at any angle. The ratio of the length _aerator / width _{venting device} is advantageously greater than 1. The cover is at least as large as the vent opening so that the vent opening is completely covered by the cover. In an advantageous configuration, the cover extends beyond the vent opening where it forms an opening with the surface material.

  The venting device is advantageously arranged in an area of increased sweating. In order to effectively protect the body against cold air even in extreme climatic conditions, in a particularly advantageous configuration, the venting device comprises a fastener, for example a slide fastener or a hook fastener or a snap fastener.

  The ventilation opening may penetrate only the surface material, but may penetrate the surface material and the lining, or may penetrate the surface material, the membrane, and the lining. In this case, the vent opening may be completely open or may comprise an air permeable material, such as a mesh. The opening formed with the surface material by the cover may also be completely open or may comprise an air permeable material, for example a mesh.

  In the following, the best mode for carrying out the present invention will be described in detail with reference to the drawings. An advantageous configuration is illustrated. However, the present invention is not limited to this configuration. The protection scope of the present invention applies to all configurations shown in the specification.

  The configuration shown in the drawings shows the outerwear according to the invention with enhanced breathability. The outerwear partially shown in FIGS. 1-3 has a vent opening or venting device. The venting device comprises at least one vent opening 1 and a cover 4 that can be closed by a fastener tongue 7. This cover 4 is located on the surface material 3 of the wear. The cover is curved over the vent opening 1 and has a predetermined distance a from the vent opening 1 along the longitudinal axis. The cover 4 is fixed to the surface material 3 at the side edge 5 and the upper edge 6, and forms an opening downward together with the surface material 3 in an open state.

  According to FIG. 1, a surface material 3 with two vent openings 1 is shown. The cover is not shown here to make the drawing easier to see. The ventilation openings 1 are located side by side, and are cut out so that the web 2 remains between the openings. The web 2 prevents the vent opening 1 from maintaining its shape and being pulled apart. This ensures that the cover 4 curved over the ventilation opening does not rest on the ventilation opening and does not obstruct the ventilation.

  According to FIG. 2, a surface material 3 with a ventilation device consisting of two ventilation openings 1 and one cover 4 is shown. The opposite side of the cover extends in parallel. The cover is connected to the surface material 3 on three sides, that is, a side edge 5 and an upper edge 6 and forms an opening with the surface material downward. In order to make the drawing easier to see, the fastener tongue 7 is not folded inward in this drawing. In the illustrated configuration, the fastener tongue is fixed in a desired position by the snap fastener 8. A press button located inside the cover 4 for fixing the position of the fastener tongue 7 folded inward is not shown in the drawing. Further, the cover may be molded as described above. The connection between the surface material and the cover shown in FIG. 2 is a seam. This bonding may be done by gluing, welding or another known bonding technique or a combination of these processes in addition to sewing. The length of the cover is at least as large as the length of the opening. In the configuration shown, the cover extends below the opening below. According to FIG. 2, a venting device without a fastener mechanism is shown.

  FIG. 3 shows a cross-sectional view of the vent opening along the cutting axis entered in FIG. It is shown how much the cover 4 is curved over the vent opening 1 and has a predetermined distance a relative to the surface material 3. The cover is preferably curved over the vent opening in an arcuate or semicircular shape. Although the ventilation opening only penetrates the surface material 3, it may penetrate the surface material and the backing or the membrane (membrane). In this case, the vent opening may be completely open or may comprise an air permeable material, such as a mesh. FIG. 3 shows a surface material without a backing or membrane.

It is a figure which shows the surface material provided with two ventilation openings. It is a figure which shows the surface material provided with the ventilation apparatus which consists of two ventilation openings and a cover. It is sectional drawing of the ventilation opening along the AA axis line written in FIG.
